2024-09-10btrfs: more efficient chunk map iteration when device replace finishesFilipe Manana
When iterating the chunk maps when a device replace finishes we are doing a full rbtree search for each chunk map, which is not the most efficient thing to do, wasting CPU time. As we are holding a write lock on the tree during the whole iteration, we can simply start from the first node in the tree and then move to the next chunk map by doing a rb_next() call - the only exception is when we need to reschedule, in which case we have to do a full rbtree search since we dropped the write lock and the tree may have changed (chunk maps may have been removed and the tree got rebalanced). So just do that. Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
2024-09-10btrfs: reschedule when updating chunk maps at the end of a device replaceFilipe Manana
At the end of a device replace we must go over all the chunk maps and update their stripes to point to the target device instead of the source device. We iterate over the chunk maps while holding a write lock and we never reschedule, which can result in monopolizing a CPU for too long and blocking readers for too long (it's a rw lock, non-blocking). So improve on this by rescheduling if necessary. This is safe because at this point we are holding the chunk mutex, which means no new chunks can be allocated and therefore we don't risk missing a new chunk map that covers a range behind the last one we processed before rescheduling.
